Long-term exposure of Daphnia magna to polystyrene microplastics induces changes in their proteome.

ABSTRACT: In the past years, the research focus on the effects of microplastics (MP) on aquatic organisms extended from marine systems towards freshwater systems. An important freshwater model organism in the MP field is the cladoceran Daphnia, which plays a central role in lacustrine ecosystems and has been established as a test organism in ecotoxicology. To investigate the effects of MP on Daphnia magna, we performed a chronic exposure experiment with polystyrene MP under strictly standardized conditions. Chronic exposure of D. magna to PS microparticles led to a significant reduction in body length and number of offspring. To shed light on underlying molecular mechanisms induced by microplastic ingestion in D. magna, we assessed the effects of PS-MP at the proteomic level.

Single Cell RNA Sequencing Analysis of Polystyrene Microplastic Exposed and control Zebrafish Intestine

Project description:Microplastics (MPs) as widespread contamination pose high risk for aquatic organisms. However, current understanding of MP toxicities are based on cell population-averaged measurements. Here we used single-cell RNA sequencing to provide the transcriptome heterogeneity of 12000 intestinal cells obtained from zebrafishes exposed to 100nm, 5μm and 200μm polystyrene MPs (PS-MPs) for 21 days. Eight intestinal cell populations were identified. We found that all the three sizes of PS-MPs induced dysfunction of intestinal immune cells (including phagosome and regulation of immune system process).

Oyster reproduction is affected by exposure to polystyrene microplastics

Project description:Plastics are persistent synthetic polymers that accumulate in the marine environment as waste. Microplastic (MP) particles are derived from the breakdown of larger debris or can enter the environment as microscopic fragments. Filter-feeder organisms ingest MP while feeding and are likely to be impacted by MP pollution. To assess the impact of polystyrene microspheres (PS) on the physiology of the Pacific oyster, adult oysters were experimentally exposed to virgin micro-PS (2 and 6 µm in diameter; 32 µg L-1) for two months during a reproductive cycle. Effects were investigated on transcriptomic responses, in digestive gland gonads and oocytes of exposed oysters. Transcriptomic profiles in the tissues of the exposed oyster showed endocrine disrupting signals, notably highlighting alteration in glucocorticoid response, insulin pathway and fatty-acid metabolism in response to micro-PS exposition. In oocytes from exposed females, several transcripts coding for proteins involved in Ca2+ binding were differentially expressed suggesting a disruption of the Ca2+ signaling pathway with crucial consequences on oocyte maturation.

The Daphnia cuticle proteome - whole cuticle samples

Project description:The cuticles of arthropods, including aquatic crustaceans like Daphnia, provide an interface between the organism and its environment. Thus, the cuticle’s structure influences how the organism responds to and interacts with its surroundings. Here, we used label-free quantification proteomics to provide a proteome of the molted cuticle of Daphnia magna, which has long been a prominent subject of studies on ecology, evolution, and developmental biology, anddetected 278 high confidence proteins. Using protein sequence domain and functional enrichment analyses, we identified chitin-binding structural proteins and chitin modifying enzymes as most abundant protein groups in the cuticle proteome.Structural cuticular protein families showed a similar distribution to those found in other arthropods and indicated proteins responsible for the soft and flexible structure of the Daphnia cuticle . Finally, cuticle protein genes were clustered as tandem gene arrays in the Daphnia genome, indicating their importance for adaptation to environmental change. The cuticle proteome presented here will be a valuable resource to the Daphnia research community, informing investigations on diverse topics such as the genetic basis of interactions with predators and parasites.

D. magna CT448 protease specificity

Project description:Mass developments of toxin-producing cyanobacteria are frequently observed in freshwater ecosystems due to eutrophication and global warming. These mass developments can partly be attributed to cyanobacterial toxins, such as protease inhibitors (PIs), which inhibit digestive serine proteases of Daphnia, the major herbivore of phytoplankton and cyanobacteria. To date, mechanisms of this inhibition in the gut of the crustacean Daphnia magna are not known. Here, we characterize a single serine protease, chymotrypsin 448 (CT448), which is present in the gut of the crustacean D. magna.

Whole organism transcriptomic analysis provides mechanistic insight into the acute toxicity of emamectin benzoate in Daphnia magna

Project description:This experiment was conducted to study the short-term (12h) transcriptional responses in Daphnia magna after exposure to the anti-sea lice chemical emamectin benzoate (EMB). The microarray results were further vefiried using qPCR. The gene exression responses were linked to adverse effects after 48h exposure, in order to supply knowledge for environmental hazard assessment of this chemical in non-target crustaceans. Neonatal (<24h) Daphnia magna were exposed to 7.8-2000 pM waterborne emamectin benzoate for 12h. Microarray analysis was performed using pooled whole-organism D. magna (8 individuals) and 4 biological replicates were analyzed for each treatment group.

Evaluation of chronic sublethal effects effects of the organophosphate flame retardant Tris(2-butoxyethyl)phosphate (TBEP) using Daphni magna transcriptomic response

Project description:The aim of this study was to measure chronic sublethal effects of the flame retardant Tris(2-butoxyethyl)phosphate (TBEP) on gene expression, associated protein activity and life-history endpoints (reproduction, development) in the freshwater crustacean Daphnia magna. We exposed <24h old D. magna neonates for 21 days to culture medium (control) and to 3 sublethal doses of TBEP: 14.7, 147 and 1470 M-BM-5g/L. Exposure doses were chosen from 48h acute toxicity testing and represent 1/10000, 1/1000 and 1/100 of the LC50, respectively. Each condition (control and the 3 different doses) were performed on 3 independant biological replicates, with 10 individuals each. We used a custom 15000 sequences D. magna microarray to measure transcriptional effect of each of the TBEP doses in comparison to unexposed controls. We exposed <24h old Daphnia magna to culture medium (unexposed controls) and 3 sublethal doses of TBEP (14.7M-BM-5g/L, 147M-BM-5g/L and 1470M-BM-5g/L) for 21 days. We used 3 biological replicates of 10 individuals for each condition.

Assessment of transcriptomic and apical responses of Daphnia magna exposed to a 3 polyethylene microplastic in a 21-day chronic study

Project description:There is global concern regarding the fate and effects of microplastics in the environment, particularly in aquatic systems. In this study, ethylene acrylic acid copolymer particles were evaluated in a chronic toxicity study with the aquatic invertebrate, Daphnia magna. The study design included a natural particle control treatment (i.e., silica) in order to discern any potential physical effects of a particlefrom intrinsic toxicity of the test material. In addition to the standard endpoints of survival, growth, and reproduction, the transcriptomic profile of control and ethylene acrylic acid copolymer-exposed D. magna were evaluated at the termination of the 21-day toxicity study. No significant effects on D. magna growth, survival, or reproduction were observed in the study in comparison to both particle and untreated control groups. Significant transcriptomic alterations were induced in the highest treatment level of 2.3 x 1012 particles of the ethylene acrylic acid copolymer/ L in key pathways linked to central metabolism and energy reserves, oxidative stress, as well as ovulation and molting indicating a global transcriptomic response pattern. To put the results in perspective is challenging at this time, since, to date, microplastic environmental monitoring approaches have not been equipped to detect particles in the nano size range. However, the results of this study indicate that ethylene acrylic acid copolymer microplastics in the upper nano-size range are not expected to adversely affect D. magna growth, survival, or reproductive outcomes at concentrations up to 1012 particles/L.
